[PATCH 6.1.y 1/2] spi: s3c64xx: Use devm_clk_get_enabled()

[Sasha Levin <sashal@kernel.org>]

From: Andi Shyti <andi.shyti@kernel.org>

[ Upstream commit 20c475d21ed9326f7b1396c9bb8991b375cb6c50 ]

Replace the tuple devm_clk_get()/clk_prepare_enable() with the
single function devm_clk_get_enabled().
